The mum-of-two topped the charts after doubling sales of her closest rival, Pharrell WIliams with his single Happy.

Now one of the fastest sales of the year, her cover of Demi Lovato's Skyscraper has sold an incredible 149,000 copies.

Bailey described the winning battle for the top spot as "the icing on the cake" and said she is pleased to see the proceedings go to charity.

Talking to OfficialCharts.com, the 36-year-old from Leicester said: "Being Number 1 is absolutely amazing! It really is the icing on the cake and it means Great Ormond Street Children's Charity and Together For Short Lives will benefit from the single which makes it extra special."

The former prison officer is now the proud owner of the X Factor's first Christmas number one since Matt Cardle's release of When We Collie in 2010.

It is also the X Factor's sixth Christmas number one in nine years.

Former winners include Shayne Ward, Alexandra Burke and Leona Lewis.

Lewis, who was challenging for the festive number one this year with her single One More Sleep, was forced to settle for third spot.

AC/DC's Highway To Hell made it to fourth after an online campaign which made it the band's first ever UK top ten single.

Swedish sensation Avicii filled in at five with his smash hit Hey Brother.

The Big Reunion's charity Christmas hit of Wizzard's I Wish It Could Be Christmas also made the top 40.

A Facebook campaign to get Altern 8 to number one saw the 90s rave group return to the charts for the first time in 22 years.
